Xu Xingchen and a group of senior executives of the ship girl gathered in front of the big screen of the scientific research center, watching Neptune introduce the moon exploration plan to everyone.

As soon as this introduction started, the senior executives of ship girls from various organizations were so shocked that they shouted on the spot.

"There is life on our moon!"

"This big satellite is actually a livable planet!"

"Yellow-green? And orange plants? Aren't the plants all green? Why does this happen?"

As an information reconnaissance ship, Neptune is very powerful in collecting and organizing information and using information to answer questions.

So they answered the ship girls’ doubts one by one:

“The moon seems to be active at present.

"According to current detection and calculation information, its environment is also suitable for human survival.

"What we call livable planets are based on the standard of human beings being able to live normally. If the ship girl can survive as the standard, there will be too many livable planets...

"As for the color of plants, this is actually not a particularly special thing. Even in our world, plants are not just one color.

“There are also red and blue plants on the earth, and there was a time when it was dominated by purple.

"What color will the plant show? In fact, it means that it does not absorb any color of light, or that too much light will cause problems if it absorbs too much, so use the same color to reflect part of this light.

"And the color of the object we see is actually the color reflected by light.

"The Earth's sun is classified according to the stellar spectrum and size, and should be a 'yellow-green dwarf'. The yellow and green light is the most, so most plants are green and yellow.

"Our star should be classified as an orange dwarf, but it is the largest among orange dwarfs, only a little smaller than the sun in yellow and green dwarfs, with a lot of orange and green light.

"Of course, the green plants on the earth can survive here, and the colors will be more intense, but it is very normal for orange and yellow-green plants to appear.

"If our stars turn into huge blue stars, most of the plants on our planet will turn blue, and it's a very dazzling bright blue.

"If our stars are red dwarfs, the plants will not turn bright red, but will be close to the dark red of black.

"Because the red dwarf itself is too small, the surface temperature is too low, and the light is too weak, plants should absorb all the light as much as possible and not reflect it out and waste it.

"Black is the color with the lowest reflectivity and the highest absorption.

"If the plant has bright colors, it means that the planet has abundant illumination and a lot of energy can be wasted, and the intensity of light is also directly related to the distance.

"So, usually, the closer the planet is to the star, the brighter and more transparent the plant's colors are, and the further the distance is, the darker and thicker it is.

"There is another special case. If the planet is closer to the star and the atmosphere is relatively thin, the light will be too high when it is too obstructed.

"In this case, plants on the surface of the planet should reflect all light as much as possible to avoid being sunburned, and the color of the branches and leaves may turn pure white, or even silver-white.

"In our galaxy, on the inside of our planet's orbit, the planet with a size similar to the Earth but a shorter orbit may be white if there are plants on the surface."

When Neptune explained it, he also used the scientific research equipment around him to make a simple three-dimensional graph to demonstrate it, and mentioned the relationship between plant pigment cells and photosynthesis.

Most of the ship girls are soldiers. Even if they have scientific research ships and are familiar with technology, they basically only know about weapons and equipment.

I basically don’t know much about these knowledge that is mixed with aerospace and biology, and now I’m very eye-opening.

Xu Xingchen felt similar. While Neptune was pausing the instructions, he reached out and rubbed her hair and said with a smile:

"Awesome Neptune, I didn't expect you, an electronic reconnaissance ship, to understand these things?"

When Neptune heard the praise, he immediately raised his head proudly, but said in his mouth:

"It's all about learning and selling, it's about Sister Yuanwang's explanation, plus the situation obtained by simulation of scientific research equipment."

Xu Xingchen rubbed her hair again, looked at the other senior ship girls whose curiosity had risen, and reminded Neptune:

"Okay, good job, good job, continue to explain what you plan and the situation of the space plane you designed."

"Okay!" Neptune agreed loudly, continuing to operate the large screen to switch screens, and playing a simple demonstration animation he made.

First, the diagram of the entire lunar exploration process is displayed, and the general process of the entire lunar exploration plan is introduced with great enthusiasm.

Then switch the screen to the animation video of a big plane:

"...This is the moon space plane we prepared. It can be said to be the most extreme wing body fusion and lift body design, or the contraction, blowing and expanding flying wings.

"It is essentially a transport plane or a space plane, not seeking maneuverability, but only seeking to be able to fly, carry more things, and also being able to glide.

"The pursuit of aerodynamic performance and maneuverability is relatively limited, so it eventually became such a chubby image in front of everyone.

"Originally, the biggest difficulty in designing a space plane and the biggest difficulty in the entire operation are the question of how the space plane will take off again after landing on a strange planet.

"Although our big moon is a satellite, its size is actually twice as large as Mars. Although the surface gravity is smaller than our planet, it still has 0.5 G, which is about three times the surface gravity of the Earth's moon.

"If our spacecraft wants to land from space, the problem is relatively easy to solve. If we want to take off after landing, it will be troublesome.

"If you use vertical take-off and landing, massive fuel consumption is a trivial matter. The point is that the power of this kind of thing will seriously limit the size and weight of our aircraft.

"Unless we directly send a group of ship girls to go there and land directly on the surface of the big moon to build a simple airport, we can use a large enough space plane.

"Of course I wanted to do this, but this idea and the difficulty of this operation were directly rejected by our commander at the same time.

“She is not allowed to enter the planet’s surface for the time being!

"In other words, the planes we fly can only rub in the atmosphere on the surface of the moon at most, and cannot really enter the ground.

"The commander is worried that what we accidentally get in will cause the moon... to cause biological invasion and other problems.

"Since it doesn't land, it's simple to design. This plane doesn't even need to design a landing gear, so you can see that it's all bare under her and there's not a single hair."
